Frame synchronized room lighting
Systems are provided to facilitate imaging of a person or other target in an environment by providing modulated illumination to the target and to other aspects of the environment. Modulated illumination is provided to the target such that the target receives more illumination when a camera is capturing images of the target than during other periods of time. Modulated illumination is provided to background objects or other portions of the environment of the target such that the background or other non-target elements of the environment receive less illumination when the camera is capturing images than during other periods of time. In this way, imaging of a target can be improved by increasing effective illumination of the target while decreasing glare and other effects of illumination of background objects. The illumination can be modulated at a sufficiently high frequency that the illumination appears, to the human eye, to be substantially constant. |

Video image stabilization with enforced stabilization constraints
Techniques to improve a digital image capture device's ability to stabilize a video stream—while enforcing desired stabilization constraints on particular images in the video stream—are presented that utilize an overscan region and a look-ahead technique enabled by buffering a number of video input frames before generating a first stabilized video output frame. More particularly, techniques are disclosed for buffering an initial number of input frames so that a “current” frame can use motion data from both “past” and “future” frames to adjust the value of a stabilization strength parameter and/or the weighted contribution of particular frames from the buffer in the determination of stabilization motion values for the current frame. Such techniques keep the current frame within its overscan and ensure that the stabilization constraints are enforced, while maintaining desired smoothness in the video stream. In some embodiments, the stabilization constraint may comprise a maximum allowed frame displacement. |

Hidden Markov model generation of multi-plane random screens
Methods and systems for the in-situ creation of a halftone noise screen layer by layer. Each layer produced is a white noise uniform distributed screen, statistically similar to one generated by a uniform noise function. The generation of each layer, however, is driven by a screen state which is an error based metric on the mean screen threshold. The set of screens produced are not independent of each other; adjacent layers are negatively correlated, while non-adjacent layers are completely uncorrelated. The result of this screen creation is that for any color the variation of coverage across the viewed surface is smaller than the variation produced by randomly generated screen planes. The algorithm is computationally inexpensive and eliminates the need to store multiple screens in memory. |

Smart dynamic line management
The invention describes a method of performing re-synchronizations on a DSL line to optimize the synchronization rate of the line. The line is monitored over a period of time, and a stable SNR margin is determined, below which the line is observed to lose synchronization. Historical synchronization rates and associated SNR margins for the line are recorded, and the highest stable synchronization rate is determined as the historical synchronization rate that does not have any associated SNR margins below the stable SNR margin. The method attempts to optimize the synchronization rate of the line towards this highest stable synchronization rate. To do this, the current target SNR margin imposed by DLM is identified, for example, by interrogating the DLM system or by noting the SNR margin on the line immediately after the most recent synchronizations. Assuming the current synchronization rate on the line is less than the highest stable rate, then the synchronization rate is optimized by triggering a synchronization of the line when the SNR margin is greater than the target SNR margin plus an additional predetermined amount. The result should be an increase in the synchronization rate, and can be repeated until the synchronization rate reaches the highest stable synchronization rate. |

Spatial spreading in a multi-antenna communication system
Spatial spreading is performed in a multi-antenna system to randomize an “effective” channel observed by a receiving entity for each transmitted data symbol block. For a MIMO system, at a transmitting entity, data is processed (e.g., encoded, interleaved, and modulated) to obtain ND data symbol blocks to be transmitted in NM transmission spans, where ND≧1 and NM>1. The ND blocks are partitioned into NM data symbol subblocks, one subblock for each transmission span. A steering matrix is selected (e.g., in a deterministic or pseudo-random manner from among a set of L steering matrices, where L>1) for each subblock. Each data symbol subblock is spatially processed with the steering matrix selected for that subblock to obtain transmit symbols, which are further processed and transmitted via NT transmit antennas in one transmission span. The ND data symbol blocks are thus spatially processed with NM steering matrices and observe an ensemble of channels. |

Novel tools and techniques are provided for implementing antenna structures to optimize transmission and reception of wireless signals from ground-based signal distribution devices, which include, but are not limited to, pedestals, hand holes, and/or network access point platforms. Wireless applications with such devices and systems might include, without limitation, wireless signal transmission and reception in accordance with IEEE 802.11a/b/g/n/ac/ad/af standards, UMTS, CDMA, LTE, PCS, AWS, EAS, BRS, and/or the like. In some embodiments, an antenna might be provided within a signal distribution device, which might include a container disposed in a ground surface. A top portion of the container might be substantially level with a top portion of the ground surface. The antenna might be communicatively coupled to one or more of at least one conduit, at least one optical fiber, at least one conductive signal line, or at least one power line via the container. |

Slot array antenna
A slot array antenna includes: an electrically conductive member having an electrically conductive surface and slots therein, the slots being arrayed in a first direction which extends along the conductive surface; a waveguide member having an electrically conductive waveguide face which opposes the slots and extends along the first direction; and an artificial magnetic conductor extending on both sides of the waveguide member. At least one of the conductive member and the waveguide member includes dents on the conductive surface and/or the waveguide face, the dents each serving to broaden a spacing between the conductive surface and the waveguide face relative to any adjacent site. The dents include a first, second, and third dents which are adjacent to one another and consecutively follow along the first direction. A distance between centers of the first and second dents is different from a distance between centers of the second and third dents. |

Portable antenna
An antenna having an elongated housing open at one end and defining an interior chamber. A telescoping mast has a carrier attached at a first end and a flexible antenna attached at its other end. The carrier with the attached mast and antenna is movable between a storage position in which the carrier, mast, and antenna are contained within the interior chamber of the housing, and a deployed position in which the mast and attached antenna protrude outwardly from the housing. A spring is positioned between the carrier and the housing which urges the carrier towards its deployed position. A catch mechanism selectively holds the carrier in its stored position and, when released, releases the spring to move the antenna to its deployed position. |

Pocketed circuit board
An example circuit board structure includes: a substrate; and vias that are electrically conductive and that pass through the substrate to enable electrical connection through the circuit board structure. The substrate is thinner, and lengths of the vias are shorter, in first areas of the circuit board structure that deliver first speed signals than in second areas of the circuit board structure that deliver second speed signals and power. The first speed signals have a shorter rise time than the second speed signals. |
